Request for a hotkey to switch view between the two LCDs

I'm playing Castlevania: Order of Ecclesia, and in this game one of the screens is a permanent map. I'd much prefer that only the game screen took up all the space, so I disabled the view of the map LCD. Problem is, there is apparently no hotkey to switch views between the two LCDs, so that's impractical to use, as I'd have to manually go on View -> LCDs Layout -> Horizontal whenever I wanted to check the map. Please add a keyboard shortcut to switch between LCDs in one-LCD mode! Thank you!
